Bright Red Blood In Stool Stomach Pain – Hematochezia is the passage of fresh blood from the anus, usually in or with the stool (as opposed to mela).
The term comes from the Greek αἷμα (“blood”) and hezein (“unload”). Hematochezia is usually associated with lower gastrointestinal bleeding, but can also occur from a heavy upper gastrointestinal bleed. The difference between hematochezia and rectal bleeding is that, in the latter, rectal bleeding is not associated with defecation. Instead, it is associated with passing fresh bright red blood without stool.

Bright Red Blood In Stool Stomach Pain
In adults, the most common causes are hemorrhoids and diverticulosis, both of which are relatively large. However, it can also be caused by colon cancer, which is potentially fatal. In a newborn infant, hematochezia can be the result of swallowing maternal blood at the time of delivery, but it can also be an early symptom of necrotizing enterocolitis, a serious condition that affects premature infants. In babies, hematochezia combined with abdominal pain is associated with intussusception. In adolescents and young adults, inflammatory bowel disease, particularly ulcerative colitis, is a serious cause of hematochezia that should be considered and ruled out.
Bloody Diarrhea: Causes, Risks, Treatment
Hematochezia may be due to upper gastrointestinal bleeding. However, as the blood from such bleeding is usually chemically modified by the action of acid and yeasts, it more commonly appears as black “tarry” stools known as mela. Hematochezia from an upper gastrointestinal source is an ominous sign, as it indicates a very significant bleeding that is more likely to be life-threatening. Eating beetroot can cause harmless red stools (veturia) due to insufficient metabolism of a red pigment and is a differential sign that can be mistaken for hematochezia. Eating dragon fruit (pitaya) or blueberries can also cause red or black discoloration of the stool and sometimes the urine (pseudohaematuria). This is also a differential sign that is sometimes mistaken for hematochezia.
A complete blood count as well as a hemoglobin test should be performed when a patient develops symptoms of hematochezia. A colonoscopy may be necessary if bleeding from the colon is suspected, especially in the elderly to look for the site and many causes of bleeding such as carcinoma, ulcerative colitis, rectal varices or other lesions and in some cases an upper gastrointestinal examination may also be required look for any rapid and massive fresh bleeding from the upper gastrointestinal tract where there may not be sufficient time for the blood to change color. Rectal bleeding, or hematochezia, refers to bleeding through the anus (x). Blood is often accompanied by stool and can even form blood clots. In most cases, the source of bleeding is the colon, anus, or rectum, and may also be associated with diarrhea (x).
The source of the bleeding determines the color of the blood. The blood is likely to be bright red if the source is near the anus. If the source is the colon, anus, or rectum, the blood will also appear bright red. On the other hand, if the source of bleeding is in the transverse colon and right colon, the blood is more likely to be dark red (x).
Some patients may experience bleeding that is black, sticky and foul-smelling. This type of bleeding is called melena. Melena occurs when the bleeding is in the colon and if bacteria digest it on the way down. Therefore, black indicates that the source of bleeding is the stomach, duodenum, or small intestine. However, the source can also be on the right colon (x).
Blood Clots In Stool: Causes, Symptoms, And Diagnosis
In some cases, patients experiencing malaise may also vomit. Vomit may be bright red or brown and may look like coffee grounds (x). However, certain foods and antibiotic drugs can give the stool a red or black appearance, and patients may mistake it for black (x).
Rectal bleeding can cause bright red stools if the blood doesn’t stay in the digestive tract long enough for bacteria to break it down. If blood stays in the digestive tract longer, it looks less like blood when it leaves the body in the stool (x). The source of this type of bleeding is usually the sigmoid colon and rectum (x).
In some cases, blood can move through the digestive tract too slowly to cause bright red or black blood. In such cases, the bleeding may not be visible to the naked eye. This condition is called occult bleeding (x). Patients with occult bleeding may not notice any change in the color of their stool.
Rectal bleeding may be accompanied by other symptoms depending on the location of the bleeding. If there is massive, sudden bleeding, the patient may experience weakness, dizziness, shortness of breath, and abdominal discomfort or cramps (x). The patient’s blood pressure may also drop and they may have pale skin (x).
Why You See Blood On The Toilet Paper
This condition is the most common cause of rectal bleeding. It causes swelling of the veins in the anus and rectum. Symptoms include bleeding and a painful burning sensation in the lower abdomen. Hemorrhoids are grouped into two categories: external hemorrhoids and internal hemorrhoids (x).
External hemorrhoids are usually small, painful, visible swellings (x). They usually cause itching in the anus and hard, tender bumps near the anus. On the other hand, internal hemorrhoids can be painless, but they often cause bleeding after a bowel movement or the hemorrhoid can fall through the anus. Internal swelling in the anal or rectal veins can also cause pain and difficulty passing stool (x, x).
Treatment for hemorrhoids includes prescription pain relievers, stool softeners, or bulking agents. In some cases, swollen veins can form clots, which can cause pain and may require surgery to remove the clot (x).
Hard stools can cause the lining of the rectum to tear, which can cause bleeding from the rectum. Bleeding from the anal fissures is usually mild and bright red. The tear can expose nerves and blood vessels, causing moderate to severe pain. Symptoms of anal fissures are usually reduced with stool softeners and bulking agents, as well as frequent warm baths, high-fiber foods, and pain medications (x).

This condition causes pouches called diverticula to develop and protrude from the bowel walls (x). The main cause of diverticulitis is a lack of dietary fiber (x). When the diverticulum becomes inflamed or infected, it causes diverticulitis. This condition mostly affects people over the age of 40, because age negatively affects diverticular symptoms (x).
Dark red or brown stools are a common symptom of diverticulosis (x). This condition is usually painless and asymptomatic, but when it causes pain, the patient usually feels it in the lower left side of the abdomen. Other symptoms include continuous bleeding, fever and stomach pain. This condition is usually treated by eating more fiber-rich foods (x). However, severe cases may require surgery.
An infection in the rectal or anal area can cause rectal bleeding. The main source of such infections is bacterial dysentery, caused by salmonella and E.coli. Signs of infection include bloody diarrhea, fever, and abdominal pain. Antibiotics treat gastrointestinal (GI) infections (x).
Another common cause of rectal bleeding is inflammatory bowel disease (IBD). It most commonly affects patients in their 20s or 30s (x, x). The most common types of IBD that cause rectal bleeding are Crohn’s disease (x) and ulcerative colitis (x). The inflammation can cause small to moderate amounts of bright red blood in the rectum. Often, it is mixed with feces or mucus. Fever and abdominal cramps and pain are also associated with IBD. Bowel rest and steroid therapy can help relieve it (x).

Crohn’s disease causes rectal bleeding less often than ulcerative colitis (x). However, with Crohn’s disease, the location of the inflammation determines the severity of the bleeding (x). This condition is likely to cause rectal bleeding if it affects the colon or rectum, but is less likely to cause bleeding if it affects the small intestine (x).
This condition causes inflammation in the veins and capillaries in the walls of the colon (x). Inflamed areas may become brittle and begin to bleed. Angiodysplasia is more common in older adults (x).
This condition is characterized by swollen tissues from the lining of the colon (x). Large colon polyps may begin to bleed through the rectum. This condition can be hereditary and in some cases, polyps can become cancerous (x, x).
Both benign and malignant tumors in the colon and rectum can cause rectal bleeding. This condition usually affects people over the age of 50. However, tumors of the colon and rectum can also develop in younger people (x). Tumors usually cause minimal and slow bleeding. But advanced rectal or colon tumors can cause weight loss, constipation and changes in stool. The patient may also feel pain in the anus area (x, x).
Approach To Hematochezia: Clinical Sciences
Sometimes, rectal bleeding can result from an injury and if this is the case, it should be a serious concern. For example, a gunshot wound or a foreign object inserted into the rectum can cause trauma (x). This type of bleeding can cause widespread infection or massive blood loss (x). Rectal bleeding as a result of trauma requires immediate medical attention.
The stomach and duodenum are two of the most common sources of internal bleeding that cause bloody stools (x). For
